本文针对３００ＭＷ的Ｗ型火焰锅炉冷态模型进行研究，利用热线风速仪测量炉内流场速度。得出了不同工况的炉内Ｗ型汽流流场图谱以及最佳工况下的风量配比范围，并对不同工况流场的气流速度分布规律和湍流强度分布规律以及炉内气流充满度等进行了分析。最后，本文对冷态Ｗ型气流流场进行了数值计算，得出了与试验定性吻合的计算结果。图１２表１参５
In this paper, the cold model of 300 MW W-type flame boiler is studied, and the flow velocity in the furnace is measured by the hot wire anemometer. The flow pattern of the W-shaped steam flow in the furnace under different working conditions and the range of the air volume ratio under the best working conditions are obtained. The distribution rules of the air flow velocity and the turbulence intensity distribution in the flow field under different working conditions and the air flow in the furnace are full Degree and so on were analyzed. Finally, the numerical calculation of the flow field in the cold W-type flow is carried out, and the calculation results agree well with the experimental results. Figure 12 Table 1 reference 5
